IMPROVEMENT IN BRICK-MACHINES.

Specification forming part of Letters Patent No. 19%,763, dated July 3,1877; application iled Apri1 30, 1877.

To au whom-t may concern Be it known that I,- THOMAS JAMES, of thecounty of Baltimore, and State of Maryland, have invented certainImprovements in Brick-Machines, of which the following is aspecification and I do hereby declare that in the same is contained afull, clear, and exact description of my said invention, reference beving had to the accompanying drawing, and to the letters of referencemarked thereon.

This invention relatesft certain improvements in that class ofbrick-machines in which the clay is compressed within a removable moldhaving one or more compartments or pockets, each one of which is of asize and shape corresponding practically tothe size and shape of thebricks to be made, and in which the bricks, after the compressingoperation to which they are subjected, are forced from the pockets bythe entrance thereto of blocks similar in size to the bricks, as willhereinafter fully appear.

In the description of the said brick-machine which follows, reference ismade to the accompanying drawing forming a part hereof, and in which-Figure 1 is a sectional side elevation of the brick-machine. Fig. 2 is atransverse section of the machine. Fig. 3 is a sectional plan of thesame on the line a: y.

Similar letters of reference indicate similar parts of the invention inall the views.

Ais the frame of the machine 'secured to the bed-plate B, and C C arerails forming a track running longitudinally of the same. D is thebrick-mold,'preferably formed in two compartments or pockets, each oncofwhich is fitted to hold sufficient clay for one brick. E is a removablemold-plate supporting the mold D, and adapted for movementlongitudinally of the track upon which it rests. A block, F, located inan opening in the bedplate and between the rails C, has avertically-reciprocating movement, which movement in an upward directionis obtained by means of a shaft, c, restingwithin bearings, andprovided-with a cam, b, and a hand-lever, c, secured to the outer end ofthe said shaft. The said block F is guided in its movements by means ofbolts d extending from its under side, and a bar, e, having holesthrough which the bolts pass. `The upward motion of the block Fis,'prefe`rably, limited by the length of slot in the bed-plate, throughwhich the handlever c passes; but the same eEect is produced by thedegree of eccentricity and the position of the cam b on the shaft a. Thebrick-mold D is guided to its proper lateral and longitudinal positionson the rails, respectively, by danges f projecting from the inner sidesof the frame A, and the strips g extending from the sides ofthe mold,the ends of which strips come into contact with pins on the upper facesof the elevatory bars h, The elev'atory bars are suspended from atransverse rod, i, located above the frame by the side vbars k, asshown.

The means for operating the transverse rod i, side bars k, elevatorybars h, and the brickmold, to which` they are connected, is a lever, l,pivoted to the top of the frame A, and attached at one end to the saidtransverse rod 11. G G are stationary blocksfsecnred to the upper partofthe frame A by means of bolts, and adapted,in the upward movement ofthe mold, to enter the compartments or pockets thereof, for purposeshereinafter described.

The operation of making bricks by means of this machine is as follows: Amold-plate corresponding to the one, E, is Iirst laid upon the track atthe end thereoft represented by e, and the mold placed thereon. Thepockets in the mold are then filled with clay and the projecting. claystruck ofI". The plate and mold are then placed directly over thevertically-moving blocks F and beneath the stationary blocks G.The'hand-lever cis then moved in the direction of the arrow, whichlever, through the medium of the mechanism connected therewith, elevatesthe mold and compresses the bricks, the stationary blocks Genteringslightly into the pockets in the mold. The hand-lever c is then moved ina reverse direction, which allows the mold-plate to seat itself upon thetrack. The outer end of the second hand-lever is next depressed., whichhas the eect of elevating the mold. as before described. In thisoperation the bricks are forced.

out of the mold to the mold-plate, upon which plate they are removed tobe dried. The mold is then withdrawn and used, as before described,inconnection with another mold-plate, the 'operation being continued aslong as may be desired.

l Having thus described my invention, what I claim as new, and Wish tosecure by Let ters Patent of the United States, is-

1. In a brick-machine, the combination of the removable mold D, withmechanism for elevating the same, as described, the remova ble plate E,vertically-moving block F, and stationary blocks G, substantiallyasWherein described. l

2. As means for elevating the brick-mold D, the elevating-bars h, sidebars k, transverse rod i', and hand-lever l, combined suit1 stantiallyas shown.

3. The combination of the vertically-moving block F, the shaft a, cam b,hand-lever c, track C, mold-plate E, removable mold D, and stationaryblocks Gr, substantially as specified.

1In testimony whereof I have hereunto subscribed my name this 25th dayof April, in

the year of our Lord, 1877.

THOMAS JAMES.
